Just got an invite this morning from Coinbase to earn $6 worth of Dai by watching videos about it, I signed up to the waiting list a week ago,
You will need a Coinbase account to earn the Dai, just log into your account and go to the "Earn" section on the top left corner of your dashboard, then click the "Get Started" button to watch 3 videos about Dai and answer a question about it, each worth $2 in Dai,
The questions are easy, see questions and answers below,
1. What is Dai ?
A. A decentralised stable coin that aims to be worth one US dollar
2. What are two features of Dai ?
A. Decentralised and borderless
3. How do you generate Dai ?
A. Open a CDP with Maker
Here are some screen shots,
You can still sign up to earn up to $50 worth of Stellar Lumens (XLM) if you haven't already done so, just go here.
